The vitriol pond is a remnant of the former mining of vitriol. The mining took place here as early as 1669 and can still be recognized by the pond pit and in the surrounding forest.
The heath pond is on the edge of the Düben heath, near the small village of Reinharz. It can be easily reached via signposted forest paths. There is a resting place right at the pond for a break. ☺️👍🏻
